The total number of ducks in the study area
: In an aerial survey of four plots selected by simple random sampling, the numbers of ducks detected were 44, 55, 4, and 16. Careful examination of photo imagery of the first and third of these plots (selected as a simple random subsample) revealed..

Ethnocentric staffing policies in international operations
: Many Japanese companies use ethnocentric staffing policies in international operations. Why do you think Japanese companies prefer to have Japanese in top management positions? Would you recommend a change in this policy?

Disease using the horvitz-thompson estimator
: With the data of Exercise 1, estimate the total amount spent on medical care for the disease using the Horvitz-Thompson estimator, and estimate its variance.

Verify that an infinite sequence of augmenting paths
: Verify that an infinite sequence of augmenting paths is characterized by the table of Fig. 3.12; each augmentation increases the divergence out of the source s but the sequence of divergences converges to a value, which can be arbitrarily smaller ..

How much variability did age account for in pwv
: What was the correlation between health and education and how much variability in health could be accounted for by activity?

Spent on medical care for the disease investigated
: Using the network sample of Example 1, estimate the total amount spent on medical care for the disease investigated. The dollar amounts for the seven people linked to the three households listed in the example are y1 = 0, y2 = 3400, y3 = 5000, y4 =..

Suppose that a simple random sample
: Suppose that a simple random sample of n = 5 plots is selected from a study area of N = 100 plots and that the numbers of animals detected in the five plots are 10, 7, 0, 0, and 5, but that the probability of detection for any animal in a selected..
